To all whom it ma concern:

Be itknown t at I, Lnmvm THIELE, a subject of the Kin of Prussia andEmperor of German residing at Holland, in the county of ttawa and Stateof Michi an, have invented certain new and useful provements in Aparatus for Manufacturmg Glue, of whic the following is a specification.

My invention relates to improvements in the manufacture of gelatin andglue, and its objects are: first, to provide ameans whereby the gelatinmay be extracted from the raw material and made in much less time and atmuch less expense than by any of the methods now in use f r itsmanufacture; second, to provide a means whereby the product will berendered much stronger and more tenacious than by the processes now .inuse, and, third, to provide a means whereby the product may be bleachedwhile in process of manufacture. I attain these objects by the mechanismillustrated in the accompanying drawing in which- F1 re 1 is a sectionalelevation of the extractmg or cooking tanks practically on the line ata: of Fig. 2. Fig. 2 1s a sectional plan of the same on the line 3/ y ofFig. 1, and Fig. 3 is an elevation of the steam coils and the extractingtank, with the outside .ank removed.

Similar letters refer to similar parts throughout the several views.

In the construction of the a pliances for extracting the gelatin or gluerom the raw material I rovide a tank A, which is )rovidcd witi a watertight cover B that me a water, air and steam tight cap 6 at the apex forthe passage of the water pipe ll into the tank A. substantially as shownn. Fig. 1. Inside of this tank I place a cagc G which acts as areceptacle for the.raw material G', from which the gelatin or glue is tobe extracted. This cage is finel erforated both through the side wallsand tlie bottom, as shown at c in Figs. 2 and 3, sothat steam that isdischar ed through the pipes D, as indicated at d may thoroughly ermeateevery section of the raw material to redoes it to a jellp in theshortest possible period of time. prefer that the ca or receptacle bemade of aluminum, as t is metal has the property of avertin the dangerof diecoloring the product whi e in the process of being extracted. t

I provide two distinct means for heating ,.-..rpose of reducon the endof this pipe inside of the tank A and force water through the pi underhigh over t e top of the material in a very fim strongspray, asindicated in Fig. 1. T! water is raised to nearly or uite the boil ingpoint before being fore through Ha.

pipe H. and is superheated byva stmi p of live steam from the pipesthrough the heater G, so thatthe p is wholly surrounded and thoroughlyh. v. t. thereby. The second means for heating: material consists ofpassing live through the pipes F and F into th D, D, D between the outerand tl'n: tanks. The connectin pipes D in ti. are finely perforated trough the sides to the cage so that the live steam is against thesurface of the cage and it: w the apertures in the walls thereof, in ticontact with the material G. The rear ing steam in the coil, as itcondenses. ilowed to flow throu h the drain I after having passed t rouh the pipes t. l the lower circular pipe Th of steam through the pipeTII" wil jelly warm so that it will fit a i the filter intothereceptacha l. v out through the pipe (2 to any desire a agereceptacle.

As the material G is reduced to thc ly state, it flows through the smallapertu es 0 through the we glue before straining it through t e filteri,

saturate the animal matter G with a bleaching compound or chemical andpass another chemical solution through the pi e H so that it is sprayedthrough the spraer h upon the material G, the same as. he spraying ofhotwster as hereinlitiiore-dels and bottom of the 1 cage, into thechamber J, below, wheie its ressure so that it will be distributedscribed, thus a plying the bleaching element at the most e ective time,that is, when thegelatin or he is in its nascent state or beingextracted rom the animal matter.

For the pa ose of regulating the flow of steam to and t rou h the i es Fand F, I place a valve, as and C ,in these pipes each side of the pipeF, that ma be opened and closed at pleasure, and eac independent of theother, so that steam may be entirely shut off from either or both ofthese pipes, or may be allowed to-fiow with full force through either orboth, or the stren th of the flow may bevregulated to be forci l'e orweak through either or both of said pi es to govern the temperature ofthe materia in the tank.

, the water pipe, and a steam pipe What I claim as new, and desire tosecure by Letters Patent of the United States, is:

1. In a device for rendering animal matter to a jelly preparatory tomaking gelatin and glue, a steam ti ht tank, a cage finely perforatedthrough .t e walls and bottom, a-

and a perforated cage, a steam coil surrounding the cage, a hot waterpipe leading into the tank, a superheating appliance connect ed withsaid pipe, a settling chamber below the cage, a filtering appliancebelow the settling chamber, means-for heating the settling chamber, andmeans for drawing ott the produced gelatin or glue liquid.

3. In an appliance for reducing animal matter to gelatin or glue, asteam tight tank, an inner perforated cage, a steam coil between thetank and cage, a steam heater, a

water pipe passing through said heater, and

into the. tank, a spraying device on said pipe within the tank, a steampipe leading to the steam coil and to the steam heater, shut oil valvesin the steam pipe between the steam heater on one side and thesteam coilon the other side, a settling chamber including a filtering device belowthe cage, a receptacle below the filtering device for receiving thefiltered substance from the cage, and a siphon for drawing oil thecontents of the receptacle.
